An integer P is added to another integer...

An integer P is added to another integer Q, then the result is R. If R is -12 more than P, then find Q. Also find R when P is 42.

A

30

B

32

C

20

D

23

Text Solution

Verified by Experts

The correct Answer is:
30
P +Q = R
P + Q = P+ (-12)
Q = -12
If P = 42, R=P+Q = 42 + (-12) = 30
